Abstract (en)

A recovery toner classifier (1) includes a rotatable cylindrical-shaped filter (9) and a fur brush (3) having a brush (3a) spirally provided on an outer peripheral surface of a rotation shaft (12). A non-brush region (3b,3c) is continuously formed from the inlet (5a) of the filter (9) for the recovery toner through the outlet (6) of the filter (9) for discharging the disposal toner along the axis line of the rotation shaft (12). The fur brush (3) integrally rotates with the rotation shaft (12) with a tip portion of the brush (3a) being in press-contact with an inner peripheral surface of the filter (9). A screw conveyer (4) having a screw (13) on a portion of the rotation shaft (12) on a side of the inlet (5a) of the filter (9) for the recovery toner is provided to convey the recovery toner to the inlet (5a) of the filter (9) for the recovery toner. <IMAGE>
